SCOTUSblog:  “On January 10, the Court will hear oral arguments in Knox v. Service Employees International Union (SEIU).  At issue in the case is whether a public sector labor union that imposes a temporary mid-year fees increase to be used for political purposes must provide employees with a separate “Hudson notice” that explains how the fees were calculated and gives employees an opportunity to object.  Even before it reaches that question, however, the Court must consider whether the case is still alive or has instead become moot.”
